At NREL’s Energy Systems Integration Facility (ESIF) in Golden, Colo., scientists and engineers work to overcome challenges related to how the nation generates, delivers and uses energy by modernizing the interplay between energy sources, infrastructure, and data.

When the Building and Construction Authority (BCA) in Singapore needed to retrofit its three-story building on the BCA Academy campus, it decided to try to make it a net zero energy building despite the challenge of doing so in a hot and humid tropical climate.

When designers of the first net zero energy school in the U.S. considered how they would approach the lighting design differently using today’s LED technology, the results extended far beyond just switching out the lightbulbs.
